The Mares Avanti Quattro has been loved by every diver from instructors through to newcomers for over 20 years. Ask any instructor what his favourite fin is and he will tell you the Mares Quattro's.

But in recent years the newer technology in some other competitors had left them behind in terms of weight versus performance - but not any more!

When you have a fin that is so right then the only thing to do with it is make it lighter so that we can take them on holiday with us!

The Mares Avanti Quattro Plus Fins feature their Channel Thrust technology for maximum efficiency.

They now come with a bungee strap as standard and weigh half as much as the old version! If you want power, performance, manoeuvrability and the ability to frog kick all at a great price - then look no further!

  • Bungee strap
  • Hi-flex material optimises blade’s efficiency
  • Four channels for greater thrusting power
  • Stabilising trim tabs
Material: Thermoplastic rubber-Tecralene®
Blade: 38cm (size R)
Weight: 0.9kg (size R)
Blade Thrust Area: 780cm² (size R)
